OF SAME PLACE.

IMPROVEMENT m HAY-ELEVATORS.

Specification forming part of Letters Patent No. 177,203, dated May 9, 1876; application filed April 24, 1876.

To all whom it may concern Be it known'that 1, WILLIAM CARROLL, of Indiana, in the county of Indiana and 'State of Pennsylvania, have invented certain new and useful Improvements in Hay-Elevators, of which the following is a specification:

Figure l is a side elevation. Fig. 2 is a detail, showing the revolving catch. Fig. 3 shows the latch reversed.

The object of the present invention is, to provide an effective operating device for elevating and moving hay and the like; and it consists more particularly in such construction and arrangement of the several parts of the carrier and its adjuncts, and the hoisting mechanism, that it can be easily and securely placed in position, and operated under all the ordinary conditions required in use, all as will now be more specifically and in detail set out and explained.

In the accompanying drawing, A denotes the carrier-frame hung upon and movable over rod B, which is usually a little inclined, by means of roller a. At the top, and near the rear of this frame, the end of the latch O is.

pivoted or hinged in or to ears a Said latch thence extends forward and beyond the front of the frame. When the latch is down its fore part rests in and upon the groove in the edge of the front wheel. Its front end is pointed and rounded on' the under side, and has the usual notch c in it, which is adapted to engage easily upon a suitable edge or bar, d, in the catch D; also, nearsaid forward end, and on the under side of said latch, there is a downward projection, O, which is adapted in the movement of the frame upon the catch to act as a stop. The rod B passes through the catch D, and said catch may be thus self-adjustable or oscillated, or turned upon said'rod as an axis. It may be so hung that it will be counterbalanced, and thus always stand with the edge or bar d upward; or it may be weighted, as now shown at d, for the same purpose.

The latch may be lifted for the purposes of releasing it from the catch, or otherwise, by means of perpendicular bars E E, operated upon by block F. Said bars, as now shown hay.

in dotted lines, may be pivoted at c,- or when they only extend up to the end of bars E they can be pivoted there at 6 and E -will be-pivoted at e.. In either event the construction and operation are aimed to accomplish a like end.

The bars E are sustained in part, and have their motion regulated, by pins 0 attached to them, and working in slots a of the frame A. In E or in the upper ends of the bars E, according to construction specified above, are slots 0 through which passes pin a uniting the two sides of the frame, and helping to constitute also support-for the said bars when down, and serving as a guide when the bars are moved vertically to open or close the latch. The lower end orjaws of the bars E have shoulders on the inner and contiguous faces at E upon which the swivel-head f of block F may be securely but flexibly held, the shank of said head fitting into proper depressions in said shoulders. On the lower side of the block is the fork or usual means for attaching the The lower end or jaws of said bars will be opened on raising the block F by means of a rope, which passes over its pulley, and thence over pulley G, in the lower part of the frame, and extends to any-point convenient for the user. When said block is thus raised, its

rounded upper end fitting into the flaring mouths. of the said jaws or ends throws them apart and the bars E upward, and thus the vertical motion, heretofore referred to, is communicatedto the latch by the connection at c, and causes it to rise, thereby releasing the frame from conjunction with the catch D. This catch and the frame which carries the latch can have free vibrating or oscillating motion. This is of importance oftentimes in the handling of hay or the substance which' is being elevated, and prevents strain and danger of breaking the several parts.

The latch may beheld in position by means of detents b b, which may be rigidly affixed, or so as to be moved at will upon rod B at its highest or outerend. The movement of the latch end upon the catch causes the bars to rise, and these being thrown apart by the movement of the pins 0 in the slot a the jaws are opened and the swivehhead falls out pf ilts seat, thus releasing the block and its om a If desired to make the latch reversible, I place ears a on the side of the carrier opposite to those at a, and pivot the end of the latch in a, and their middle ate. It may sometime be desirable also to have the forward end of the latch bent, as now shown in Fig. 3. The various changes can all be readilyadapted to the apparatus. Having thus described my invention, what I consider new, and desire to secure by Letters Patent, is p a 1. The combination of pivoted bars E E 1 with frame A and latch G, substantially as and for the purposes set forth.

2. The combination of bars E, having shoulders E with block F, having swivel-head f,

substantially as and for the purposes set forth. 3. In combination with frame A, carrying bars E E and hinged latch O,\the revolvable catch D d at, substantially asdescribed;

4. In a hay-elevator, substantially as described, the latch G, having shoulder O", and

constructed to operate in conjunction with catch 1 substantially as described.

5.'The combination, in a hay-elevator, of frame A, provided with slots at, pivoted bars E E E having pins 6 working in said slots, pulley F f, with latch O a G, and revolv'able catch D, substantially as set forth.

6. The reversible latch (J, in combination with frame A, and cars a a, substantially as and for the purposes set forth. a

"In testimony that l clail'nthe foregoing as my own I affix my signature in presenceof two witnesses.
